Description

Technical Field

[0001] This application relates to the field of environmental protection technology, and in particular to a method, system and electronic equipment for determining the vegetation configuration pattern of riverbanks. Background Technology

[0002] Currently, under flood conditions, water flow exhibits obvious non-uniform flow characteristics, and the resistance of floodplain vegetation is relatively large, affecting the flood discharge of the river channel. Domestic and foreign studies have focused more on the configuration types of riverside vegetation and hydrological connectivity, and less on low-resistance configuration patterns. In particular, the understanding and research on the process of changes in river vegetation resistance along the course under non-uniform flow conditions are not deep enough, which makes it impossible to accurately determine the vegetation configuration pattern for rivers under non-uniform flow conditions. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The specific operational methods in the method embodiments can also be applied to the device embodiments or system embodiments. It should be noted that in the description of this application, "multiple" is understood as "at least two". "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. A connected to B can represent: A and B directly connected, and A and B connected through C. Furthermore, in the description of this application, terms such as "first" and "second" are used only for distinguishing the purpose of description and should not be construed as indicating or implying relative importance or order.

[0034] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 The diagram shows a flowchart of a method for determining a riparian vegetation configuration pattern according to this application. The method includes:

[0036] S1, determine the flow type corresponding to the current riparian zone and obtain the vegetation hydrodynamic parameters of each aquatic vegetation;

[0037] Specifically, in response to the severe sandification and insufficient soil fertility in sandy river corridors, ecological revetment has been constructed through soil improvement, selection of pioneer plant species, and the construction of ecological revetment in accordance with vegetation configuration patterns, thereby creating riverbank zones in sandy river corridors.

[0038] To achieve the above approach, it is first necessary to screen pioneer plants. Therefore, in this application embodiment, vegetation parameters of various types of aquatic vegetation are obtained. These vegetation parameters include at least one or more of the following: growth parameters, chlorophyll parameters, nitrogen content parameters, and enzyme activity parameters.

[0039] By using the above screening rules, aquatic plants that meet the preset conditions can be selected from various types of aquatic vegetation, that is, dominant species suitable for growth in sandy riverbeds can be selected.

[0040] In this embodiment, pioneer plant species were selected based on experimental data: tamarisk, juniper, lespedeza, lilac, and cogongrass. Based on similar experimental data from the literature, plant species were selected as follows: yellow rose, apocynum, poplar, ground ivy, sulfur cosmos, buffalo grass, sedum, alfalfa, ice plant, potgum, clematis, lysimachia, iris, and crown vetch. Finally, cogongrass, tamarisk, lespedeza, apocynum, and potgum were determined as candidate species. Among these, tamarisk and cogongrass are amphibious plants and can be planted at the boundary between riverbanks and beaches as transitional plants.

[0041] After screening pioneer plant species, ecological revetment screening was conducted. Based on considerations of revetment stability and safety, the soil erosion control capacity and pollutant reduction capabilities of different ecological revetments were analyzed. The influence of water flow on revetment materials and structural forms was explored, and safe and stable ecological revetment forms suitable for sandy river channels were selected. Through analysis of data such as hydrodynamic parameters, total nitrogen and total phosphorus reduction rates, and shear stress changes in ecological revetment screening experiments, typical revetment experiments, and pilot-scale revetment experiments, five ecological revetment forms were selected: (lead wire) gabion revetment, willow pile revetment, riprap + earth gabion bag revetment, earth gabion bag revetment, and grass seed-sown revetment.

[0042] After completing the screening of pioneer plant species and ecological revetments, the flow type corresponding to the current riverbank zone is determined, and the vegetation dynamics parameters of each aquatic vegetation are obtained. These dynamic parameters include, but are not limited to, the drag coefficient and roughness coefficient under different aquatic vegetation configuration patterns. The aquatic vegetation dynamics parameters allow for the analysis of experimental data changes under different configuration methods, submersion levels, orientations, and densities.

[0043] S2, Determine the vegetation spatial configuration pattern based on the obtained vegetation hydrodynamic parameters;

[0044] After determining the vegetation hydrodynamic parameters, vegetation spatial configuration patterns with low flow resistance can be screened out. These patterns characterize the spatial relationships between various types of vegetation.

[0045] Furthermore, in this embodiment of the application, it is also necessary to determine the specific vegetation spatial configuration pattern based on the shore flow, such as configuring the vegetation space of different spatial units according to the spatial units of "flat beach flow" and "floodplain flow" and the selected plant species.

[0046] S3 determines the vegetation configuration mode corresponding to the current riverbank based on the flow type and vegetation spatial configuration mode.

[0047] After determining the specific plant species and bank protection methods based on the methods in steps S1 and S2, the vegetation configuration mode corresponding to the current riverbank can be determined according to the specific flow type and vegetation spatial configuration mode.

[0048] Specifically, the explanations will be based on "plain flow" and "floodplain flow" respectively. In the floodplain vegetation configuration pattern, this pattern reflects the function of soil stabilization and slope protection. Based on the slope ratio, combined with soil improvement and landscape effects, it is divided into the following three patterns:

[0049] Mode 1:

[0050] The soil slope protection vegetation configuration pattern (Tamarix + Juniperus sabina + Populus tomentosa + Imperata cylindrica + Agrocybe aegerita + Iris tectorum) is used for slopes primarily for soil stabilization and slope protection. This pattern employs a staggered arrangement of plants with well-developed root systems, using a sparse and permeable structure. In the flow direction, the vegetation is arranged with sparser vegetation in front and denser vegetation behind. In the overflow direction, a non-uniform configuration is used, with sparser vegetation at a stem density of 20-40 plants / m², and the width of the sparse vegetation configuration covering 60% of the entire forest belt width.

[0051] Mode 2:

[0052] Soil-improving vegetation configuration (Juniperus sabina + Lespedeza bicolor + Alfalfa + Buffalo grass + Coronelm chinensis + Apocynum venetum), configuration: sparse vegetation planting density of 20-40 plants / m², dense vegetation planting density of 90-110 plants / m². The width of the sparse vegetation strip should be 50%-70% of the total vegetation strip width.

[0053] Mode 3:

[0054] Landscape enhancement vegetation configuration (lilac + poplar + yellow rose + sedum + weeping elytra + sulfur cosmos): Shrubs and herbs on the beach are arranged in streamlined patches parallel to the overflow direction, with parallel vegetation within each patch. The width of the vegetation patches is 3m–5m, and the spacing between patches is 2m–3m. The vegetation is planted in an arc shape on the flow-facing side of the patches, with parallel strips arranged within each patch.

[0055] Furthermore, in the flatland vegetation configuration pattern, this pattern reflects the function of soil stabilization and slope protection. Based on the slope ratio, combined with soil improvement and landscape effect, it is divided into the following two patterns:

[0056] Mode 1:

[0057] The landscape enhancement vegetation configuration (Gnaphalium affine + Imperata cylindrica + Cosmos sulphureus + Alfalfa + Corona vulgaris + Potentilla chinensis) uses streamlined patchwork shrubs on the riverbanks, with the planting direction parallel to the overflow direction and at an angle of 30°–45° to the river channel. Within each patch, the vegetation is planted in parallel, with a density of 40-50 plants / m². Herbaceous plants are also planted parallel to the overflow direction, with parallel planting within each patch. The width of the vegetation patches is 3-5m, and the spacing between patches is 2-3m. The vegetation on the upstream side of the patches is planted in an arc shape, with parallel strips arranged within each patch, and the planting direction is at an angle of 30-45° to the incoming water flow.

[0058] Mode 2:

[0059] Habitat restoration vegetation configuration pattern (Leymus chinensis + Sedum lineare + Buffalo grass + Sophora flavescens + Imperata cylindrica + Agrocybe aegerita) Configuration method: Herbaceous plants are sown in patches, with a patch width of 3m to 5m, a spacing of 2m to 3m between patches, and a herbaceous sowing density of 1kg / 100m2.

[0060] Based on the methods provided above, pioneer plant species and ecological revetment forms can be selected. Combined with low-obstruction vegetation composite configuration technology, the ecological environment of sandy riverbanks can be restored. Ecological revetments can be constructed based on the riverbank slopes, and plant species can be planted on and off the revetments to form an ecological riverbank belt construction technology.
